| Term | Definition |
|---|---|
| water | Water is a clear, tasteless, odorless liquid (\(H_{2}O\)) made of two hydrogen and one oxygen atom, essential for life, found in oceans, rain, and living things, and can exist as solid (ice), liquid, or gas (steam) |
| polarity | molecules have a slight positive end (hydrogen side) and a slight negative end (oxygen side), like tiny magnets, due to uneven electron sharing |
| surface tension | the "skin" on a liquid's surface, caused by molecules pulling inward, making the surface act like an elastic sheet that resists external forces and tries to shrink to the smallest area possible, allowing small objects to float |
| capillary action | the ability of a liquid (like water) to flow upwards in narrow spaces, defying gravity, due to the combined forces of adhesion (liquid sticking to the tube) and cohesion (liquid sticking to itself) along with surface tension |
| cohesion | Cohesion in water is the natural "stickiness" where water molecules are attracted to and bond with other water molecules, forming strong internal attractions (hydrogen bonds) that make water behave as a cohesive unit |
| adhesion | Adhesion in water is the tendency of water molecules to stick to other substances, like glass, plant stems, or skin, rather than just to each other |
| capacity | how much water a container (like a bottle, bucket, or pool) can hold when it's full, measured in units like milliliters (mL) or liters (L) for liquids - its about how much it can hold (like heat) |
| temperature | how hot or cold water feels, technically measuring the average movement (kinetic energy) of its molecules, expressed in Celsius or Fahrenheit, and it's crucial because it affects aquatic life, oxygen levels, and chemical processes. |
| agent | a substance that causes a specific effect or reaction |
| climate | long-term patterns of ocean and atmospheric conditions, like average temperature, salinity, & currents; dictate marine life & regional weather; large water bodies (oceans) act as giant heat regulators, creating milder coastal climates |
